Will the AVR-S670H damage the Stage 240H?

No. Without Dolby Atmos or DTS:X decoding, the AVR-S670H simply has no height channel to send to the Stage 240H.

What impedance setting should I use for the Stage 240H on the AVR-S670H?

None: the Stage 240H is 6 Ω, and the AVR-S670H needs no change for it.

Is the AVR-S670H powerful enough for the Stage 240H?

Comfortable. From a seat 2 m away, loud 95 dB movie peaks take about 26 W per speaker, and the AVR-S670H is rated 75 W per channel. Cinema reference level, 105 dB peaks, takes about 253 W.
